DETACHABLE WHEEL.

Specification of Letters 'Patent Patented Aug. 29,' 1911.

Application inea November 11, 1910. serial no. 59mm.

ToI all whom l'it may concern:

Be it known that jI, BARTON BERKLEY HILL, a citizen of the United States of America, residing at 29 Princess May road, Stoke Newington, London, England, have lnvented certain new and useful Improvements in Detachable Wheels, of which the following is a specification.

`This invention relates to detachable wheels for motor propelled and other vehicles and particularly to the type of wheel-,f

provided with a num-- the hub of which is ber of holes to receive pins carried by a anged shell, which is free to rotate on the axle bt is restrained from moving axially thereon, the hub being locked on said pins by suitable means. c

'The object of the present invention is to facilitate the locking of the hub on the pins and in such a manner that after the hub is slid onto the pinsa mere partial rotary movement given to a member thereon by means of a Spanner or other tool, will sufce to lock the hub on all the pins simultaneously. Another object of 1 the invention is to cause an automatic tightening or'loosening ofthe hub on the pins according to the d1- re'ction ,in which the aforesaid rotary movement is applied. c

With the above objects in view the invention comprises a shell having-pins, a wheel hub having holes to receive said pins, a" locking member carried by the wheel hub, but so as to be free to. rotate thereon, 'said `member having means which, when the said member is partially rotated, coact;,w1th meansV on lock Vthe hub on back off thehnb according to the direction in'r'which` said memberis rotated.

The inventionalso comprises a lock for the lookin member, and other details hereinafter re .erred to.

'In' the accompanying drawin is a side view of one formoy 1i" 're l detiiliable wheel hub accordingI to the invcntion-,- B

broken-awa to show some-o evices 'for t e pins. Fig. yil is .a sectional elevation corresponding 4of it bei Inekng front. thereto Int abella, provided withall ila d on theend of the axe c, 1n 4any the aforesaid pins to lock or un-V the pins and to draw on 0 1` 'rotary movement `a farm if the invaniin illustrates, a

b, and is v rotary, movement ofthe lockin' usual manner. so that it 1s free to rotate thereon, but isrestrained from movin ax iallyV in relation thereto. The mo e of moon-tin the shell a', on the axle forms no part of t 'e present invention. The flange b, 'V

l1s provided with a number of. pins d, and the body 4o'f the shell is provided with feathJ ers or lzeys e, forente'ring' corresponding re-I cesses in the wheel hub4 f. The hub f, carries the vspokes g5 inany'usual manner and the lian' e It, of4 the hub is rovidcd ,with holes so t at the hub can'be slid on to the pins d. Thli;4 outer ends of the pins d, are slotted as atI v A rotary locking member l, provided with a hexagonal sleeve m, for'recei'ving a spanner -or like tool, is furnished with a numi'ber of locking devices in the form of cams n,

adapted 'to enter thepslots c, i`n the pinsv d, when the rotary locking member l, is parrotated. The 4cams n, are in 'such nuV 'er and are so disposed on the member l, t at when the latter 1s in one position and the wheelV hub is slid on to the pins d, the latter pass through -the spaces o, (Fig. 1) between the cams n, a slight rota movementgof the member Z, resulting in t e cams n, enterin all the slots k, simultaneously and there y locking the hub on'the pins. The cams areiof such inclination that when they enter the slots 7c, theydirnpart an axial movement to the hub relatively to the shell a., tending to tighten the hub thereon. The Ymember -Z, is itself then locked by a lock as to avoid accident movement of the ymember Z, due toV vibration. A rubber washer r,` is preferably 4 inserted between the lock nut p, and the ange s, of a cap t, which is screwed into the end of the hub.

When the wheel is to be detached: a spanner' or other tool is ap lied to the lock 1nut and the hexagonal s eeve m, and a. slight is` imparted thereto in the to thatl adopted to 'lockthe hub,-wherei1pon all the cams nl leave their slots to release the hub onY the pins This reverse, movement of the," n, ialso re- `salts in a slight axialmovement lof.` the hub andi. ia back it of th-pins d, and .nasen it' on e shell a. It will thus' be Vunderstood that by a slight' member 1,1m

ub is locked c reverse direction one direction or the other the ion operiite with -tlie ends of said pins 'when said member is partially rotated relatively to the hub for the'purpose of locking the hub on the pins, substantially as hereinbe fore set forth.

2. A detiichiible Wheel Comprising a shell hiii'viiig pins provided with grooves, .fi hub.

having holestoreceive said pins, a rotary locking member on the'liu'b adapted to rotate relatively thereto, a plurality of' in* Wardly extending cams on the rotarydocking. member which engage the grooves inthe piiis,-'Whereby t0 'simultaneously look all the pins, and. means for fastening the rotary locking' member.

3. A detachable Wheel comprising a shell having slotted pins, a hubv having holes to receive said pins, a locking member carried by thel hub and adapted tobe rotated relatively thereto, zuid cams on ssiiii member for n l v comming with the slots on the aloresiiidpins, siil'stuiitinlty is lfiei'einbclore set forth.

'L .X delmrhnble 'wheel f'foml'irising i shell hiiviiig ai thinige, pins projecting from siiid [hinge :ind having.; slots in 'their ends, u. hub liiiviii'g` holes to receive sind pitre', i rotary locking` member carried by the hub and lieviiig Cams.' iidiil'ited to enter and recede from the slotsin thesaid pins when. said locking member is partially rotated relatively to the hub, and a look iiiito ii the hiib for said rotar; locking inembeii, substantially iis :ind i, purpose liereitibetoie described.

A de-ti'ielizible wheel comprising'zi shell ing pins, :i h'ub'haviiig holesto receive said pms, a rotsiry lockiiig'member on the hiib.ii tilepted to rotate relatively thereto, said member having means -or izo-acting with the said pins to lool; the hub'thereto, and having i hexagonal extension substantially as and for the purpose hereiiibe'fore set forth.

`In testimony whereof I affix my .signature iii the prt'ssenee of two witiji'esses.
